Former Heavyweight Champion Brock Lesnar Informs UFC of Retirement

Multiple outlets confirmed on Tuesday that the ex-heavyweight
champion has notified the UFC of his decision.
MMAFighting.com first reported the news. Because Lesnar is no
longer on the roster of the Las Vegas-based promotion, he has also
been removed from the United States Anti-Doping Agency Drug Testing
pool.

Lesnar was suspended for one year by both USADA and the Nevada
Athletic Commission after testing positive for the estrogen blocker
clomiphene in both an in- and out-of-competition drug test in
relation to UFC 200. He would have been eligible to return to
competition on July 15, 2017. Lesnar would have to complete the
remainder of that suspension should he decide to end his retirement
at any point.

In his first bout in more than five years, Lesnar defeated Mark Hunt via
unanimous decision at UFC 200, but that result was overturned to a
no contest following the results of the drug tests. Lesnar
initially retired from the UFC following a first-round technical
knockout loss to Alistair
Overeem in December 2011.
